I'm marking comment 0 private, since it contains log files from the customer.

I'm not aware of supporting UDF installation media in the past, so I'm marking this bug as a request for a new feature.

Hi could you please provide us kickstart file? It seems that you are loading installation source/environment from the kickstart and we would need to know what command is used there.
